LU BRICATOR.

SPECIFICATION forming part of Letters Patent No. 264,176, datedSeptember 12, 1882.

Application filed July 17, 1882. (No model.)

To all whom it may concern:

Be it known that I,'JO11N B. LOW, a citizen of the United States ofAmerica, residing at Falls Village, in the county of Litchfield andState of Connecticut, have invented certain new and useful Improvementsin Lubricators; and I do hereby declare the following to be a full,clear, and exact description of theinvention,such as will enable othersskilled in the art to which it appertains to make and use the same,reference being bad to the accompanying drawings, and toletters orfigures of reference marked thereornwhich formapart of thisspecification.

This invention relates to new and useful improvements in lubricators;and it consists in providing a float which is made of a material whichislighterthau' the lubricatingsubstance, which tloat will be held by itsown inherent buoyancy against the journal or other object to belubricated, as will be hereinafter setforth, and pointed out in theclaims.

On the annexed drawings, Figure 1 isa sectional view, showing myinvention applied. to a car-axle bar. Fig. 2 is a view of the samedetached, and Fig. 3 is a detailed perspective view of the guides.

A represents a cylindrical float or lubricator, which is made ofsuitable'buoyant material, cork or other light substance answering thepurpose well. This float is supported in the oil-well or other liquidreceptacle upon a suitableframe, B,\vhich isprovided with guides C 0,having longitudinal grooves 01, through which pass the guide-rods b b.

By the use of the lubricatorherein described packing or other devices toconvey oil to the journals are dispensed with, and the roll A, by itsown inherent buoyancy, is kept in contact with the journal as long asthere is sufficient oil in the well to float the same, and its pressureagainst the object to be oiled is so slight that there is but littlewear of the parts, and its simplicity is such that there are no parts tobreaker get out of order.

By means of the slotted guides C and journals the roller A is heldsecurely in place,and is capable of a vertical and rotary motion withoutdanger of displacement by a longitudinal movement. The guides C do notinterfere or remove the oil from the roller, as would evidently be thecase if the guides were arranged so as to bear upon the sides of therollers.

This invention may be put to other usesthan for oilingthejournalsofmachinery without departing from the spirit of my invention, as thedevice illustrated in Fig. 2 of the drawings may be set in or upon acup, and maybe employed as a finger or stamp moistener for use incounting-rooms, as an article of stationery, or desk-furniture.

What 1 claim as new, and desire to secure by Letters Patent, is-

l. The roller A, made of buoyant material, journaled loosely at its endsin slotted guides, the whole being attached to an open frame, B,substantially as shown, and for the purpose set forth.

2. The roller A, composed of a buoyant material, and provided with endjournals, I) l), in combination with the guides C C, having verticalslots ac, and frame B. substantially as shown, for the purposes setforth.

In testimony whereof I affix my signature in presence of two witnesses.

JOHN B. LO\\.
